The UN panel on climate change says greenhouse gas emissions must start falling by 2025 to limit global warming to 1.5 degrees Celsius. He says deep reductions must follow in order to prevent climate change from having a serious impact on the environment.
On Monday, the Intergovernmental Panel on Climate Change published a report on measures to be taken to combat global warming.
A working group has been holding online meetings since March 21. He discusses the latest research results. The publication of the report follows these discussions.
The report notes that emissions have continued to rise globally in recent years. It says the reduction targets that each country has pledged to achieve by 2030 are not enough to limit the temperature increase to 1.5 degrees above pre-industrial levels.
The report says greenhouse gas emissions must peak before 2025 at the latest. He adds that they must be reduced by 43% compared to the level of 2019 by 2030 and by 84% by 2050.
The panel calls for major transitions in the energy sector, which accounts for a third of all emissions.
It calls for a substantial reduction in the use of fossil fuels, such as oil and coal, and a transition to renewable energy sources, such as solar and wind power.
But the panel says it will be difficult to meet the targets with renewables alone. He suggests using alternative fuels, such as hydrogen, and using energy efficiency systems.
IPCC Chairman Hoesung Lee said the latest report presents clear evidence that it is still possible to curb climate change.
Lee said, “We are at a crossroads.” He added that it was time to act. He said: “We have the tools and the know-how to limit global warming.”
A special report will be published by the IPCC in September. It will combine the report released on Monday with reports previously released by other IPCC working groups.
Lee expressed his expectations for the UN climate change conference COP27 to be held in Egypt in November.
He said the IPCC special report will help policy makers in countries attending the conference decide what action to take.
